摘　　要：以南京长江新济洲国家湿地公园最大的洲滩新济洲为研究对象,以2008年7月的高分辨率遥感图像Quick Bird、2008年13个鸟类聚集区的空间分布数据为主要信息源,在传统"千层饼模式"生态适宜性分区基础上,结合研究区域的鸟类景观安全格局构建,对适宜性分区方案进行优化调整。研究表明:研究区域鸟类的景观安全格局由4个源、3条生态廊道、2个战略点构成;生态适宜性分区优化后,2条生态廊道所经地段由低生态适宜区变为生态较适宜区;经过优化,研究区域建设用地、农地、苗圃等低适宜区,面积比例下降7.34%,草本沼泽、森林等较适宜区、高适宜区面积比例,分别上升了6.37%、0.37%。The largest marshland Xinjizhou at Yangtze Xinjizhou National Wetland Park was chosen as the case study area, while the high resolution remote sensing image of QuickBird in July, 2008, and 13 spatial distribution data of birds gathering were collected as the main source of information. Then ＂layer-cake model＂ based ecological suitability was analyzed and bird landscape security pattern was constructed, followed by optimization of suitability partition. Studies show that： the bird landscape security pattern in study area birds is comprised of four sources, three ecological corridors, and two strategic points. After optimization, the crossed places by two ecological corri- dors has been transformed from the low ecological suitability area into the appropriate ecological zones. Compared with the original partition plan, the percent of low ecological suitability area of construction land, cropland and nursery land is decreased by 7.34% , the percent of appropriate and high suitable area such as herbaceous swamps, forests, is increased by 6.37 % and 0.37 %, respectively.
